[Experimental study of lincomycin ointment and gel]

Area of Science:

• Pharmacology
• Dermatology
• Toxicology

Background:

• Topical antimicrobial agents are crucial for treating skin infections.
• Lincomycin is an antibiotic with potential for topical application.
• Development of stable and effective topical formulations is essential.

Purpose of the Study:

• To evaluate the pharmacokinetics and safety of lincomycin ointment and gel.
• To assess the skin diffusion characteristics of topical lincomycin formulations.
• To determine the general toxicity and organotropic effects of lincomycin preparations.

Main Methods:

• Pharmacokinetic studies to assess skin penetration.
• General toxicity testing.
• Organotropic property investigation.
• Stability testing of ointment and gel formulations.

Main Results:

• Satisfactory diffusion of lincomycin through the skin was demonstrated for both formulations.
• No irritating effects were observed.
• No significant changes in internal organs indicative of toxicity were found.
• Lincomycin ointment exhibited favorable stability upon storage.

Conclusions:

• Lincomycin ointment and gel are safe and effective for topical use, with adequate skin penetration.
• The lincomycin ointment formulation is recommended for large-scale industrial production based on stability and safety data.
